ALL BIRDS WORTH WATCHING

This time of year some birds are still raising young, many fledglings are getting their first experience in the real world, migratory urges are starting to pull some species into flocks (swallows lined up along a powerline for example). And there’s just a lot of interesting stuff to see, if you stop and watch.

  • Recently I saw a Collared-Dove harassing a Crow.  So much for dove of peace.  I suspect the Crow was hanging around where the dove had  a nest.
  • A young House Finch has showed up in our garden, completely without any hint of bright color.
  • We have two Juncos in our garden, one male and one female.  Each has white feathers on one wing.  Siblings?  They are in adult plumage.
  • Two Red-breasted Nuthatches arrived simultaneously at our feeder recently.  One swooped in with a loud whirring sound, the usual honk just given multiple times with no rest in between.  Never heard that before and these tykes honk around our garden every day.
  • The Starlings that bred in our garage roof and then raided the feeders daily in June are gone off to join their rural cousins…I guess.  Haven’t seen them for two weeks.
  • The Anna’s Hummingbird has now found our feeder after it hung in place for two weeks.
  • We lost very few of our blueberries to birds.  I am pleasantly surprised.rbn flat (1280x960) spto-1 (1280x960) spto-fed (1280x960) sqrl-a (1280x960) sqrl-b (1280x960) sqrl-c (1280x960) (1280x960) sqrl-D (1280x960)

HONEYGUIDES REALLY ARE

There’s article in today’s “NYTimes” on how man and honeyguides interact, to the benefit of both in southern Africa.

We see more passive interplay between man and bird with TVs, raptors, crows or gulls following hay mowing machines in America.  In Panama I saw both herons and caracara following a mowing tractor there.  It’s long been known that Ravens ally themselves with Inuit hunting parties in caribou country, and also work side-by-side with wolf packs.  In Europe the Robin there will often follow a gardener around, waiting for the insects and worms that may be displaced and thrust onto the Robinesque menu.  Anybody feeding birds regularly will be familiar with those that learn to demand food: hummers, Wild Turkeys, jays of all sorts.

“Where is my peanut?”

“Come refill my feeder.”

THE GREAT GRAY OWL WHO CAME TO STAY

There’s a Great Gray Owl hunting up along Steinman Road south of Ashland these days.  Here’s a picture sent to me by Brandie Lynn who is a neighbor of the visiting owl for the time being.  She’s seen the bird be a successful hunter several times.  The grassy pastures thereabouts are going to seed and attracting plenty of small rodents.ggo_BrandiLynnThis area is east of Old Highway 99 South where that road makes a loop back over itself between Emigrant Lake and Callahan’s at Exit 6 on I-5.  Elevation is 3100 feet.  Habitat is scattered rural homes in an open, dryland forest of white oak, ponderosa, scrub trees and unmown grasslands.  Most of the land is NOT used as pasture so the treeless areas and rodents are undisturbed.  A few years back Brandie had a GGO hunt from the railing on her porch.  This is the season when she sees these birds in her area.  This is likely an adult bird done with the year’s nesting and breeding duties…if, indeed, this bird nested this year.  It could be a yearling and not old enough to mate.

Brandie says this bird has been in area for a few days now.  Sometimes it is visible and active in daytime.

If you are interested in learning more about these owls, here’s information on the book about them that was written by Peter Thiemann and I.

LATE JULY: BASKETT SLOUGH

Shorbird season is upon us.  A short visit to Baskett Slough this afternoon yielded five shorebird species.  Best spot of the trip, though, was a single Black Tern.  Also there were juveniles of both Coot and Pied-billed Grebe splashing about.2 BY 2--COOT PBG Grebes on right with zebra-striping.  Coots on left and below.YNG COOT (1280x960)One of each: PBG TWO (1280x960) LEANIN GREG (1280x960)     SPSA AFAR (1280x960)Spotty above, dowitchers on the far side  of pond (below):SHORE5 (1280x960) TWO GBH (1280x960)Meadow of mint: MINT MEADO (1280x960) BIG MINTNutria: NUTRIA IN POND (1280x960)

THE YOUNG AND THE RESTLESS

It’s almost dark and 930PM as I write this.  A Barred Owl is hooting not far from my open window here in McMinnville.

It’s dispersal time here in Yamhill as both young and old birds leave breeding areas to wander in search of good eating.  Today there were five Spotted Sandpipers at Yamhill Sewer Ponds today.  A month ago: none.  At least two were white-breasted fledglings.sp (1280x960) Spott-Juv1 (1280x960) SPOTT-JUV2 (1280x960)GBH-A1 (1280x960) GBH-A2 (1280x960)Streaked throat means this is a juvenile heron.

SORRY STATE REQUIRES AVIAN THERAPY

The human world is such a sorry mess right now I need plenty of bird time.  Here’s another blogger’s version of how his garden activity keeps him going.

So to help myself to feeling less a part of the outside world, I have been going through old images from previous bird outings.  Here are some goodies, presented randomly:nor shrikNorthern Shrike, above, at Nisqually.  Wilson’s Warbler , male.P2720765 (1280x960) P2720832 (1280x960)Sora family NIGHTHAWK IN DAYTIME Sora, Malheur.sora closeOrchard Oriole, vagrant spotted at Page Springs a couple years back.  This bird was an Oregon lifer for Slan Contreras after my Klamath Bird Observatory group first spotted it. orch-oriole (2)Sagebrush Sparrow eyeballing cameraman.

BLOWING IN THE WIND

In the air: Vaux’s Swifts, Turkey Vulture, an occasional Bald Eagle…and spider webs. Most of the webs around our garden are built by small spiders and are attached to structures and trees.WEB1 WEB2Click here for a link that shows spider weaving an orb web…in slo-mo with pianist accompaniment.

Web-weaving spiders have several spinnerets on their abdomen. Each spinneret produces a SPECIFIC kind of silk, of which there are several varieties, some thinner than others, some sticky, some simply used for structural strength.

The web silk is quite thin and can only be seen because of reflected light.  The silk is strong enough to stop an insect in flight, yet it is also flexible and can stretch up to 40% (nylon can do about 20%).  Yet the silk has more strength than steel fibers of the same diameter.  Spiders have been evolving their use of silk for at least 100-million years.

The web silk contains a lot of protein and the spider often eats the web on the morning to re-capture that protein.

Here’s description of spider silk on a University of Bristol website: “The dragline silk of the Golden Orb-Weaving spider is the most studied in scientific research.  Spider silk is a natural polypeptide, polymeric protein and is in the scleroprotein group which also encompasses collagen (in ligaments) and keratin (nails and hair).  These are all proteins which provide structure.  The protein in dragline silk is fibroin (Mr 200,000-300,000) which is a combination of the proteins spidroin 1 and spidroin 2.  The exact composition of these proteins depends on factors including species and diet.  Fibroin consists of approximately 42% glycine and 25% alanine as the major amino acids.  The remaining components are mostly glutamine, serine, leucine, valine, proline, tyrosine and arginine.  Spidroin 1 and spidroin 2 differ mainly in their content of proline and tyrosine.”

SHOREBIRD SEASON BEGINS

I saw my first migrating shorebirds of the season today, a pair of Least Sandpipers picking tidbits out of the scum along the edge of one of the Yamhill city sewer ponds.LESA1 lesa2These Leasts are adult birds.  The juveniles are still back on the breeding territory which only extends as far south as southern Alaska and the Yukon Territory. lesa3I tried to pish out a Song Sparrow and got this officious female Anna’s Hyummingbird instead.  I had just been watching her buzzing around with her two new fledglings in the willows at Wennerberg Park.anhu fml anhummBronw Creeper, Yamhill Sewer Ponds: BC ON OAK BC ON OAK2 BC ON OAK3 BC ON OAK4 BC ON OAKI3 Bewick’s Wren, Yamhill S.P.
